41 Claims.

The invention relates to new and improved methods and apparatus for applying covers to containers and more particularly to machines for applying covers of pliant material to containers, and especially such covers as hood covers or caps for bottles and the like. It is particularly concerned with the application to containers of a pliant covering material such as thick paper which is secured to the containers by shaping and folding parts formed integral with the material of the covers and which elements may also be assisted by suitable cement or adhesive means as distinguished in general from such auxiliary fastening devices as metallic means.

An object is to provide an improved container cover applying mechanism in which the cover applying means are of a non-rotary or stationary type. Certain aspects relate to the provision of a double or duplex capping mechanism and the association therewith of a particularly advantageous arrangement in feeding and transfer means adapted to operate on containers of the bottle type.

Further features reside in the improved means for feeding the blank covers or caps; in the provision of a cover applying mechanism for pleated hood covers having improved pleat forming means and the combination therewith of suitable skirt folders.

Another object is to provide a cover applying,

mechanism which includes improved means for folding'or tucking one or more depending skirt tabs upward between the container neck and the adjacent skirt parts.

Still another object is to combine an improved pleat forming means with a plurality of folders including one or more folders of novel construction for tucking a depending skirt tab between the container neck and the skirt.

A further object is to provide a cover applying mechanism which includes a novel arrangement of folders of three forms, one for folding untabbed skirt sections, one for folding tabbed skirt sections and one for skirt tabs.

Another object is to provide a machine adapted for applying such covers in which certain of the contacting and securing parts are pre-coated with plastic cement. p

A container cover applied in accordance with the principles and methods disclosed presents a smooth, attractive appearance and possesses ample strength for the purpose intended.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

eral steps and the relation of one or more of such steps with respect to each of the others, and the'apparatus embodying features of construction, combinations of elements and arrangement of parts which are adapted to effect such steps, all as exemplified in the following detailed disclosure, and the scope of the application of which will be indicated in the claims.

The preferred embodiment of the invention includes a suitable frame structure such as 2, on which ismounted a duplex container cover applying mechanism at the upper part and which mechanism -is indicated in Figs. 1, 2and 3 of the drawings 'by 3. There are container feeding or supply means at the lower part indicated by C in Figs. 2, 4, 6 and 9, container transfer mechanism D shown in Figsa l, -5, 6 and 9, and container discharge means E shownin Figs. 1,2, 4 and 9.

The container feeding means comprise means for arranging uncovered or uncapped containers in contact in single file or series, and means to spread the containers apart sufiiciently to present them at a proper distance to be acted on by the duplex cover applying mechanism B. The container transfer mechanism then-delivers the containers in such spaced relation to the duplex cover applying mechanism B.

The cover applying mechanism then applies covers or caps simultaneously to a pair of -containers, the transfer mechanism again functions to deliver them to the container discharge means and the container discharge means then removes them to a suitable place of delivery.

Referrin to Figs. 2, 4, 5 and 6 it will be seen that the mechanisms B, and D are mounted on a base member such as indicated by 3 preferably forming part of the frame structure 2 and which is preferably supported by columns or legs, such as 4. Preferably there is a motor unit for driving the machine and it can be of any suitable form such as indicated by 5 and may be supported in any suitable way as by mounting it on a shelf 6 secured to the legs 4 below the base member 3. Preferably the motor unit is provided with a speed adjusting means suitably operated as by the hand wheel I, the turning of which causes the movement of a screw 8 by which the motor is moved to and fro and different speeds attained through the medium of an automatically adjustable tension pulley 9. The tension pulley 9 of the motor unit is provided with a driving belt 1!! carried around a driven pulley H secured to the shaft [2 of a speed reduction unit I3. On the shaft I2 is also secured a worm M which drives the worm wheel I5 secured to the lower part of the vertical shaft I6 which is journaled in bearings 16a in the speed reduction unit. The shaft [6 also has secured to it at its upper part the bevel gear 22.

J ournaled'in a bearin [8 on the same axis as the shaft I6 is a vertical shaft I! on which are secured two cams l9 and '23, and a spur gear 2|. There is a coupling member 23 secured to the shaft l6 just above the bevel gear 22 between the latter and the cam 23 to which it is secured by bolts 23a.

Mounted on the base member 3 is a reciprocating carrier member 24 forming the base part of the transfer mechanism. This may be supported for reciprocation in any suitable manner but preferably as follows: Located in the base member 13 are two Vertically arranged bearing sleeves 25 which journal the vertical shafts 26. Secured to the upper parts of each shaft 23 is an eccentric 2'! havinga shoulder 28. The securing means Fig. 8.

The cam 20 causes the longitudinal movement of the member 24 through the medium of the anti-friction roller 34 mounted on the short arm 35 which is secured to the lower end of the vertical shaft 36 journaled in the bearing hub 31 of the base member 3. On the upper end of the shaft 33 is secured the long arm 33 to which is pivoted the link 39 said link being pivotally connected to the member 24 at 40. Thus rotation of the cam 23 causes oscillation of the arm 35, shaft 35 and arm 38 and consequent lengthwise reciprocating movement of the member 24.

Transverse reciprocation is also imparted to the member 24 at certain times by the mechanism shown in Figs. 5, 7, 8 and 12. At the lower end of each of the vertical shafts 26 is secured a pinion gear '4! which meshes with the teeth of a rack bar 42. The rack bar 42 is slidable to and fro in the channel of the bar 43 suitably secured to the frame structure 2, said bar 42 being just above the plane of the top of the cam 20. There is a bell crank 44 pivoted at 45 to the base member 3 and having an anti-friction roller 41 movable by the-cam 20 on the side of the shaft l1 opposite the roller 34. Pivoted to the rack bar 42 at 48
